Laparoscopic surgery specimen bag

Abstract

The invention relates to a laparoscopic surgery specimen bag which comprises a bag body and an air tube. A bag opening of the bag body is of a double-layer structure composed of an outer layer and an inner layer. An inflation cavity is formed between the outer layer and the inner layer, and communicated with the air tube which is connected with an air valve. The air valve is composed of a rope, a valve body, a chock plug and a blocking handle, and the valve body is a shell body which comprises a straight rod cavity and a hopper cavity. Two ends of the valve body are open, and the hopper cavity end of the valve body is communicated with the air tube, and a limit hole is formed in the side wall of the straight rod cavity of the valve body. The chock plug is arranged in a containing cavity in the shell body, and one end of the chock plug is of a cone column matched with the hopper cavity. The other end of the chock plug is fixedly connected with the rope, and the blocking handle penetrates through the limit hole, and one end of the blocking handle is fixedly connected with the chock plug. The laparoscopic surgery specimen bag can conveniently and quickly finish taking out specimens, and inflation and disinflation of the bag opening of the specimen bag are carried out in the abdominal cavity. Therefore, a normal laparoscopic surgery can not be affected due to untight sealing.

Description

technical field [0001] The invention relates to a medical device, in particular to a specimen bag used in laparoscopic surgery. Background technique [0002] Surgical laparoscopic surgery inserts instruments into the abdominal cavity through a 5-10mm diameter Trocar placed on the abdominal wall. The resected specimens are as small as the appendix and gallbladder, as large as kidneys, tumors, etc., and need to be placed in the specimen bag through a small incision of 10mm Trocar or After a little extension, it is taken out to achieve the purpose of minimally invasive surgery. When taking out the specimen, it needs to be put into the specimen bag to avoid falling into the abdominal cavity, rupture of the specimen, contamination of the wound, etc. It is often difficult to open the mouth of the common specimen bag currently used after being put into the abdominal cavity by Trocar. Even if the mouth of the bag is opened, due to the softness of the mouth of the specimen bag itsel...

AI Technical Summary

Problems solved by technology

It is often difficult to open the mouth of the common specimen bag currently used after being put into the abdominal cavity by Trocar. Even if the mouth of the bag is opened, due to the softness of the mouth of the specimen bag itself, the process of loading the specimen is time-consuming and laborious.

When the specimen is loaded and taken out, it is necessary to repeatedly clamp the mouth of the bag with laparoscopic operating instruments. During the process of taking the specimen out of the abdominal cavity, the specimen bag will fall into the abdominal cavity if one is not careful, or the specimen will slip out of the bag, causing If the operation fails, someone once proposed to leave a long rope on the bag mouth to pass through the Trocar outside the body of the patient, ignoring that laparoscopic surgery is performed in an artificial pneumoperitoneum. When the instrument is inserted into the Trocar for operation, the seal will not be tight and air leakage will occur. , and even lead to surgical failure
